Guys, one of our boxes just died with the following error: kernel panic - not syncing: fs/block_dev.c:396: spin_lock (fs/block_dev.c:c0361c0) already locked by fs/block_dev.c/287. The system's an LVS running CentOS 4.3: centos-release-4-3.2 kernel-2.6.9-34.EL ipvsadm-1.24-6 heartbeat-1.2.3.cvs.20050927-1.centos4 I note that there's a bug report filed related to CentOS 4.2: http://bugs.centos.org/view.php?id=1201&nbn=7 I was just wondering, would you like a bug report filed for this? Will.

THIS IS A TESTING KERNEL !!!! :) You can get it like this: place the testing repo file in /etc/yum.repos.d/ ... the repo file is here: http://dev.centos.org/centos/4/CentOS-Testing.repo Then you can get the testing kernel (or kernel-smp, kernel-hugemem. etc) with the command: yum --enable-repo=c4-testing install kernel (or kernel-smp, kernel-hugemem, etc.) (did I mention this was a testing kernel ... :) -------------- next part -------------- A non-text attachment was scrubbed...

Cheers. Will.
